Biomechanics of Spiral Fractures: Investigating Periosteal Effects Using Digital Image Correlation

This study presents a novel integration of high-speed digital image correlation (DIC) with paired biomechanical testing to evaluate the periosteum's role in spiral fracture formation-an area that remains underexplored. The findings offer new insight into the strain distribution dynamics in immature long bones and highlight the periosteum's potential protective contribution under torsional stress.
